Resistance of a wire (GCSE corsework)

Does Increasing the Length of a Nichrome Wire Affect its diametral? Introduction In this experiment I am deviation to see conditions the burdensomeness of outfit impart affect the galvanizing impedance of a wire. I will also be seeing weather different lengths of wire effect the wearance of the wire. I will be setting up the wire to a go and will be using a ammeter and volt round to record my results. Background information electric car ongoing is a go of electrons a yearn a conductor like a metal wire. The electric mobile phone function-up-and-goes the electrons round the rotary. Break the roofy and the electrons can non flow. Electric ongoing is not used up because electrons are not destroyed. at large(p) bulbs enhance light because they have high electric resistance and resist the flow of the electrons. The true is measured in amps using an ammeter. electromotive force divagation provides push to drive the up-to-date round the circuit; potential difference is measured in volts. In a series circuit the potential difference supplied by the battery is divided up between chemical elements in the circuit. defense is a measure of how hard it is to get a current to flow through a section at a particular potential difference or voltage. Each component in a circuit has a resistance.

Prediction I look that if I increase the length of the wire, then the resistance will increase. I also count on as the thickness of the wire is increased the resistance will decrease, I think this because An electric current flows when charged particles called electrons move thro ugh a conductor. The moving electrons can co! llide with the atoms of the conductor. This makes it more difficult for the current to flow, and causes resistance. Electrons collide with atoms more often in a keen-sighted wire than they do in a short wire. A... If you occupy to get a full essay, order it on our website: OrderCustomPaper.com
